HINGE Y Application led November 27, V'1929. Seria1No4v10,099.

The invention is for a compound hinge,

and has special reference to a hinge to be used on doors cooperating W1th openings of irregular or warped shape, such as the doors l of an automobile. Y Y

The main object of the invention is to provide a type of concealed hinge which will compensate for varying required movements of the upper andl lower sections oi the door, for the purpose of retaining the top and bottom edges of the door in substantially horizontal planes at all degrees of opening, also providing means whereby said hinge prevents excess angular opening of said door, and,

rom the spirit or scope of the invention or sacrifice any of the advantages thereof.

Similar reference characters'are used to designate similar parts in the accompanying drawing throughout the several views. j Referring to the drawing: f Fig. 1 illustrates the hinge as applied to an automobile door and showing the door in open position;

Fig. 2 illustrates the hinge in closed posi. tion;

Fig. 3 is a side elevation of the closed hinge.

Fig. 4 illustrates a top plan view of the Y upper hinge in open position as presented in Fig. 1; y

Fig. 5 is a general view of the hinge in open osition.

Re erence characterV 1 designates the body of an automobile or frame for a door, said door being designated by the numeral 2. The

upper and lower hinges are designated as an entirety respectively by numerals 3 and 4.l

The hinge, Fig. 5, comprises a pair of main hinge plates 5 and 6 provided with holes 7 for attachment respectively` to the door and frame, and have Vattheir upper ends, hingedly connected by pinsS, a `pair of hinged cooperating members 9 and 10,*.the axis of hinge joint V11 between..members 9 and 10 being ingangular relation 'to hinge joints 8. Hinge joints 8 arel outwardlyl disposed and hinge joint' 11. inwardlyY disposedl as indicated in Fig.;2 f, thus permitting contactfoff faces 5, 6, 9 and 1() upon complete closure of said hinge.

\ llqualiz'ersv 12 'and 13 comprise continuano tions 10i plates9 and 10-respectivelybeyond v the hinge-eyes 14 and 15, the Aends of saidl 1 continuations being arcuatelyg Vformed. Equalizers 12 and 13 are so disposed and formed as to'beair' against thefsurface 17 of 65 the mortise 16V 4when the door is Vclosed,qas also during the initial opening and final clos' ing movements ,of the door v2, thereby equaliz-y ing the action of plates 5, 6, 9 and 10 during initial opening Vand final closing movement, 7o and preventing rattling offsaid hinge when said; door is closed. j Y,

' During the initial opening and final closing jmovements, the weight of the doorzwould have a tendency lto keep plate'lO in contact 415 with the door, thereby producing a sag. Y Equalizer 13 swinging in opposition prevents this conditionvby forcing joint 11 away from Contact VWith the door'. After a slight angular kdivergence of platesv 5 and 6 is'fattained, so sag isprevented by the angularity of the complementary joints', producing a twisting action to the plates l5 and 6. Therefore, sag

is further'prevented by the resistance of the' mounted plates 5 and V6 and their attaching e5 Y means to twisting stresses. lExtensions 12 and 13 also prevent reverse buckling and consequent locking of the hinge in Vopen position by preventing interposition of hinge oint 11 in the same horizontal plane with the two 96 hinge joints 8. Y

The door and cooperating support may be mortised to receive the hinge as, indicated at 16 and 17, inwhich'eventrcomplete closure Y will be obtained between door and frame, the

hinge being thereby concealed. Y

The invention as illustrated is a preferred embodiment of the device.

I claim: f

1. In combination, a hinge, comprisinga pair of attachable body plates, hingedly connected to an angular hinge, hinge being provided with equalizers, said equalizers consisting of inward extensions of the angular hinge plates adapted to provide uniformV action of the hinge members during the initial opening 4and final closing movement ofa dooi` by cooperation with the door frame, and to prevent rattlingof said hinge members when said door is closed. y 2. In combination, a pair of body plates adapted to be attached respectively to a door and its support, said body plates being respeci tively hingedly connected to the divergent edge of the leaves of a complementary angular hinge, said complementary angular hinge p being provided With means to cooperate With adoor and its'supprort for the purpose of l equalizing the actionof said leaves during initial opening and linalclosing movement of said door and hinge When said door is in closed position, and cooperating With .said lea-ves to prevent excess angular divergence of said body plates.

3. In combination, a pairof rectangular mounting plates hingedly connected to a pair of hinge plates angularly to the connection With said mounting plates, and integral extensions beyond the angular connection, the ends of said extensions being arcuately formed and adapted to cooperate with the door and door frame during initial pening and nal 'closing movements of the oor.

4. In combination, a pair of rectangular plates hingedly connected to a pair of hinge plates angularly connected, said hinge plates being provided With means adapted to engage the supporting surfaces in opposition during initial opening and iinal closing movements of said hinge. Y In testimony whereof I have aliixed my signature. n WILLIAM A. ERVIN.
